The present invention relates to improvements in bricks and has reference more particularly to a lire brick for boilers, using oil and gas burners. v

One of the important objects of the present invention is to provide a fire brick of the above mentioned character wherein the same comprises a body portion having superimposed thereon particular shaped projections for affording means to separate the gas that usually escapes upwardly through the flue and stack, the projections acting as a fuel saver and further permitting a hotter fire to be obtained.

i5 Still a further object of the invention is to provide a fire brick of the above mentioned character that can be constructed at a very low cost, the same being at all times positive and efficient in carrying out the purpose for which it is designed, the bricks being further simple in construction and strong and durable.

Other objects of the invention will become apparent as the nature of the invention proceeds and when taken in connection with the accompanying drawings. In the accompanying drawings, forming a part of this application and wherein like reference characters designate like parts throughout the several views:

Figure lis a side elevation of my improved ire brick.

Figure 2 is a top plan-view thereof, and

Figure 3 is an end elevation 0f the fire brick.

Figure 4 is an elevationalview of a fur nace lining wall provided with the bricks constructed in accordance with the present invention.

VIn the drawings, wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral l designates generally my improved fire brick,

the same comprising a substantially rectangular shaped body 2, on the top face of'which is formed a series of projections denoted by the reference character 3. Each projection is of triangular shape in side elevation and as is shown more clearly in Figures 2 and 3, a

5 front and rear facefl and 5 of each projection gradually converge toward the upper edge 6.

A lire brick of this character is particularly adapted to be used in boilers that employ oil or gas burners, the bricks, of course,beingV suitably arranged within the boiler, about the inner periphery thereof, in a manner to constitute a lining for the boiler, and with the projections extending in the path of flow of the gases that escape upwardly through the flue and stack. e30

In Figure 4 I have shown a furnace lining wall constructed from the bricks embodied in the features of construction above noted and from a study of said ligure it will be seen that the bricks provide a lining for the side and to walls of the boiler or furnace with the teet or projections extending inwardly with respect to the furnace so as to be in the'path of theflow of gases and serve to break up the molecules of gas and carbon, so that the possibility of the carbon caking on the interior of the flues is almost negligible. l I have found -in firing large boilers that the oil or gas burners consume considerable fuel, and furthermore, burnt out fire bricks must 15 be replaced very frequently at a Verylarge expense.

Also, where a poor grade of oil is used, the necessary amount o-f steam desired cannot be obtained. These objections are all overcome ,so by the use of my improved fire brick as has been efficiently demonstrated.

The formation of the teeth like projections on the upper face of each brick will prevent the accumulation of carbon and will further act as a means for breaking up the particles (fnf fuel to aid in the proper burning of the While I have shown the preferred embodi ment of my invention, it is to be understood that various changes in the size, shape, and arrangement of parts may be resorted to, without departing from the spirit of the'invention or the scope of theappendedclaim.

Having thus described my invention, what I claim as new is:

In a fire brick of the class described, a sub-y stantially elongated.V rectangular body, teethlike projections formed onV the upper face thereof inwardly from the opposite longitu- Y maggie Adinal edgesof the body, saidv projections being of triangular shape in side elevation, the opposite side faces of each projection tapering gradually towards the apex, said projections being arranged on said body in longitu-v dinal alinement, the endmost of said projeotions .beingdisposed inwardly from the ad;
